Hi, emre
I'm so sorry for late reply, but really I need that to be solved , here is the scenario:
We have a fresh fish restaurant in which Guests select their Fish and ask for grill, cooking, etc., and they were given a metal Plate with a Number i.e. [Ticket Tag]and just start the Ticket order starts with Fish and still not closing the Ticket, in some cases some of these Guests of this [Ticket Tag] already went in place and take a table and mention the [Ticket Tag], the Waiter starts their order for other A-la Carte menu using his/here IPAD and closes the Order. in the mean time the first guest who asked for the fish just closed the ticket on the main Cashier which produces a duplicate ticket.
Guests now finishes their eating and come to the main Cashier to Settle the Ticket, two tickets will be their, but we need only one receipt for the guest.
I hope that you get what I mean.
Many thanks.
